Forest ecosystem productivity is strongly linked to site nutrient availability, which influenced by litter inputs and their decomposition rates. Fine roots mycelia are key contributors in belowground soil carbon (C) accumulation, but studies have seldom reported how C input related types boreal forests. In this study, three mature one young Pinus sylvestris forests along a type gradient southern Finland were chosen for measurements of fine root biomass, longevity, below- aboveground growth phenology annual from tree understorey vegetation. Site distinguished vegetation composition, indicated the fertility. biomass per stand basal area decreased significantly nutrient-poor nutrient-rich sites, sites with longer longevity resulted an equal site. Above- 131–236 70–91 g m−2 year−1, respectively. Aboveground increased fertility, resulting into having decreasing trend 37% 23% total increasing Ectomycorrhizal understory production contributed 8–13% 18–41% production, Contribution was lower than that trees at xeric sub-xeric equaled mesic Our study showed distinct dimensions types. Moreover, we emphasize ectomycorrhizal addition those should always be considered balances reporting conifers.
